To all whom it may concern:

Be it known that I, PRESTON H. SELLERS, a citizen of the United States, and a'resident of East St. Louis, Illinois, have invented certain new and useful Improvements in Steam- Condensers, of which the following is a speciication containing a full, clear, and exact `description, reference being had to the accompanying drawings7 forming a part hereof.

y invention relates to a steam-condenser particularly'adapted for use in ice-manufacturing plants and the like.

The object of my invention is to construct a simple inexpensive steam-condenser which may be used singly or in series and which will furnish the water of condensation to the reboiler at a tem erature as near the boilingpoint as is possib e.

A further object of my invention is to arrange a series of baiiie-plates on the interior of a sbeam-condenser in order to cause the steam to traverse al tortuous path through the condenser, thus remaining a longer time therein than if it passed direct from the inlet to the outlet.

A further object ofmy invention is to arrange an adjustable cooling-water pipe immediately above the steam-condenser in order that the supply of water will be at all times discharged evenly over the surfaces of the condenser.

A further object of my invention is to construct a condenser wherein the interior surfaces thereof, together with the surfaces of the baffle-plates, may bel easily and quickly cleaned.

, To the above pu oses my invention consists of certain nove features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a condenser of my improved construction. Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is a vertical section taken longitudinally through the cent'er of my improved condenser. Fig. 4 is an enlarged detail section taken on the line 4 4 of Fig. 3.

The body 1 of my improved condenser is constructed of suitable sheet metal, such as galvanized iron, and is in the form of an elongated tank, the side walls of which are riveted together at their upper edges, which side walls extend from the point where they are joined downwardly and outwardly on slight angles, and the bottom 2 of the body is rounded. Heads 3 are fixed in the ends of the tank thus formed, and extending through one of said heads is an inlet-pipe 4.

Leading downwardly from the bottom of the tank adjacent the opposite head 3 is 'an outlet-pipe 5, through which the water of condensation passes to the reboiler.

Located in the up er end of the last-mem tioned head 3 an extending outwardly therefrom is a relief-valve 6 of any suitable form, which is adapted to automatically open when the steam-pressure within the tank becomes excessive.

Located on the interior of the tank and riveted thereto is a series of vertically-disposed baille plates 7, and through the lower ends of an alternate pair of these baille-plates are steam-openings 8.

Through the upper ends of the remaining pair of bafflelates are the steam-openings 9, and throug the bottom of this last-mentioned pair of baffle-plates are small drainopenings 10.

Riveted to the inner face of one of the side walls in each compartment formed by the baille-plates 7 and immediately in front of said baffle-plates are the proiecting fian'ges 11, which are normally closed by the screwplugs 12.

Extending transversely between the side walls ofthe tank 1 and in the center of each compartment therein are suitable stay-rods 13, the ends of which are fixed to the side walls of the tank in any suitable manner Fixed to the center of the tank at the top thereof is a saddle 14, and supported thereby is an inverted-T connection A15, to which are connected the inner ends of a pair of waterdischarge pipes 16, which extend longitudinally in both directions immediately over the top of the tank 1 Connected to thc union 15 is a funnel 17, into which discharges thc pipe 1S, which delivers the cooling-water.

In thc top of theI pipes 16 are the longitunally-extending slots 1S), and closing the ends of said pipes 16 arel caps 20.

Fixed on top of the ends of the tank l are brackets 21, and extending downwardly thercinto are screw-bolts 22, thc upper ends of which are forked to receive the outer ends of the pipes 16.

Nuts 23 are located upon the screw-bolts and normally rest on top of the brackets 21.

In the practical use of my improved con- IOO IIO

.time

denser the steam enters the tank through the supply-pipe 4 and passes alternately beneath and over the various barile-plates 7 in said tank, as indicated by the arrows in Fig. 3, and by the time said steam enters the last compartment at the right hand of the tank it has become Condensed, and the water of condensation, which is extremely hot and close to the boiling-point, discharges through the outlet-pipe 5 and is delivered to the reboiler. The water of condensation readily iiows along the bottom of the tank through the large steam-openings 8 and through the small drain-openings 10 and finally passes out through the pipe 5.

The cooling-water discharging into the funnel 17 from the pipe 18 passes outwardly through the longitudinally-extending pipes 16 and discharges therefrom through the slots 19. The water falling from the pipes 16 discharges onto the acute a ex of the tank 1 and flows thence downwar ly over the sides of the tank and iinally leaves said tank at the lower end of the rounded bottom thereof. Thus the cooling-water is evenly distributed over the` entire sides and bottom of the tank,-V which action, together with the retarding of the steam in the tank by means of the baflieplates, very rapidly condenses said steam.

By manipulating the' nuts 23 the screwbolts 22 are raised or lowered to change the elevation of theends ofthe pipes 16, so as to cause an even flow or distributiorof the cooling-water from said pipes. This adjustvment is not possible where the cooling-water discharges from a trough or pipe which is rigidlyixed to the top of the tank, as very often one end' of the tank is lower than the other.

When it is desired to clean the interior of `the tank and the faces of the bathe-plates,

the screw-plugs lln'ay be removed, and a hose and suitable cleaning instruments are 'inserted through the openings in the sides of the tank, which are normally closed by said screwlugs, These o enings are preferably locate adjacent to t e front faces of the baffle-plates in order that any oil which is mixed with the steam and whichis deposited on said baille-plates, together with scale or other sediment, may be easily and quickly removed.

A condenser of my improved construction is simple, strong, and durable, and while condensin the steam perfectly keeps the water of con ensation at avery high temperature, in which condition it is delivered to the re boiler. The cooling-water is delivered evenly l over the entire sides and bottom of the condenser-tank, and said tank ,can be easily cleaned and-,is self-draining'. Condensers of my improved type are usually located on top of a building or an elessaaec vated structure and are therefore practically exposed to the atmosphere and elements, and it very frequently happens that the building or structure will settle or sag slightly on one side or the framework will warp as a result of variation in temperature.

Where the Water-discharge pipe is rigidly fixed on top of the tankand one end of said tank settles slightly, the cooling-water will only discharge over about one-half or onethird ofthe sides of the tank, and to remedy this it is necessary to lift one end of the entire tank, whereas by my improved construction the water-discharge pipe can be readily adjusted so as to occupy a true horizontal plane, and thus the cooling-water will be equally discharged at all points along the top of the tank.

I claim- 1. The combination; with a condensertank of inverted-tiy shape in cross-section, of a series of brackets fixed on top of said tank, screw-bolts extending downwardly into said brackets, the upper ends of which screwbolts are forked, nuts located upon the yscrew-bolts on top of the brackets, and a water-discharge pipe arranged in the forked upper ends of the screw-bolts and. provided throughout its length with a longitudinallyextending slot substantially as specified.

2. A. condenser, constructed with a tank of inverted-iff7 shape in cross-section and having its lower end rounded, vertically-adjustable members arranged on said tank adjacent its ends, a longitudinally-slotted water-discharge pipe carried by said adjustable members, a series of baille-plates arranged on the interior of the tank, there being steam-passages formed through the lower ends of certain of the baille-plates, there being steampassages formed through' the upper ends of the lalternate baille-plates, there being drainopenings formed'in-the lower ends of the last-mentioned bae plates, there being clean-out openin s formed in one sideof the condenser imme iately infront of thebaffleplates, and screw-plugs normally closing said lein-out openings;A substantially as speci- 3. The combination with a condenser-tank of inverted-V shape in cross-section, of a water-discharge pipe arranged immediately over the apex o said tank, and adjustable supports arranged between the ends of thepipe and the tank; .substantially as specified. ln testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
